Jesus Contradiction

Crucified on the cross, Jesus cried out: “Father, forgive them, for they know not what they do.” Luke 23:34

Now Luke himself reports earlier on the same Jesus who said: “But those mine enemies, which would not that I should reign over them, bring hither, and slay them for me.” Luke 19:27

Now which is which: Jesus slaying his enemies? Or enemies slaying Jesus? If Jesus possessed the miraculous power to raise the dead back to life, what was all that deadly drama about getting himself crucified dead on a cross? How did Jesus forgive himself as he obviously knew not what he was doing? Poch Suzara
